Hello,
I have had exactly the same the same issue with the Surface Laptop 3. After i contacted the store they gave me a new one straight away (this was not Microsoft but www.bol.com). The new laptop had exactly the same problem.
As i wanted to give both of the laptops back to the store with a system recovery i tried to reinstall them. Both of the laptops crashed while trying this. I have got my money back now and bought a Lenovo yoga which is working like it should, and for half the price.
Shame on you Microsoft! They should stop selling this laptop but they don’t really seem to care about their customers.
My advice to everyone: bring it back to the store and buy another laptop.
Cheers!
Jasper
